Inside the Lines

Not very good direction or script here but Betty Compson is quite good as the German spy during WW I who finds herself in Gibraltar posing as a long-lost friend of the hostess. Of course she also has access to military secrets concerning the British fleet there. Also there is her old boy friend (Ralph Forbes) who is in the military. He plays along with Compson's disguise, trying to figure out what she's up to. Which one is the real spy?

Montagu Love, Mischa Auer, Betty Carter, Ivan Simpson, Reginald Sharland co-star.

And yes that's really Compson playing the violin.
